The influences of sacrificial layer thickness and developing time on the undercut degree, as well as their effects on the morphology and dimensional consistency of bumps, are investigated. It is observed that increasing the developing time leads to a higher degree of undercut, not only facilitating the lift-off of the sacrificial layer but also resulting in an increased base radius of the metal bumps. By optimizing process parameters, we successfully achieved Au bump arrays with a base radius around 0.99 μm, top radius around 0.3 μm, and a pitch size of 1.4 μm, exhibiting height nonuniformity below 5%.
